General Introduction to Optical Coatings
This optical coating guide explores the fundamentals, types, materials, and processes, providing a detailed introduction to optical coatings for anyone seeking knowledge on this critical topic.
Quarter Wave Plates and Half Wave Plates
Wave plates, also known as retarders, are essential optical components made of birefringent materials that are designed to manipulate the polarization state of light. A waveplate alters the phase relationship between orthogonal components of polarized light, introducing a specific phase retardance. In this article, we will help you to understand quarter wave plates and half wave plates, how quarter waveplates and half waveplates change the polarization states, and explain the uses of quarter wavelength plates and half wavelength plates.
The Optical Transmission and Properties of Sapphire Windows
Sapphire Windows, often called Sapphire Glass Windows or Sapphire Optical Windows, made of single crystal synthetic sapphire (Al2O3), are becoming more and more indispensable in the exclusive fields of electro-optics due to their combination of superior optical, chemical, and mechanical properties. This article that Shalom EO presents concentrates on the optical transmission and the optical properties of sapphire windows, including the transmission wavelength range of sapphire, the transmission rate, the birefringence, and orientations. We have also analyzed the different growth methods and grades of sapphire crystals.
Laser Induced Damage Threshold Tutorial
Laser-Induced Damage Threshold, or LIDT is the highest fluence or power density of laser radiation incident upon the optical component before any unacceptable damage occurs. This article offers a basic tutorial and explanation of laser damage threshold, including the definition of LIDT. The test method of LIDT, laser-induced damage threshold for CW laser and pulsed laser, the calculation formula, the laser damage mechanisms, how to scale LIDT, the causes of laser damage, and high power laser optics/coatings.
Plastic Scintillators VS Other Radiation Detectors
This article contains a comparison of plastic scintillators against various radiation detectors, including GM counters, NaI(Tl) scintillators, proportional counting tubes, CsI(Tl) scintillators, CZT detectors, high-purity germanium detectors, and silicon semiconductor detectors from the perspective of their applications.
Explore 755nm Alexandrite Laser Optics
Alexandrite lasers are laser sources that adopt the alexandrite crystal as the laser gain medium, operating at a wavelength of 755nm, and are among the most versatile and effective laser systems available today. Their unique properties make them essential tools in both medical and aesthetic applications. In this article, we will explore the uses of Alexandrite lasers, compare them with diode lasers, and shed light on the optical components that ensure their optimal performance.
What Are Achromatic Lens Used For
An achromatic lens, often called an achromat, is a lens consisting of more than one carefully engineered lens element combined (often cemented) together, used to minimize chromatic aberration. In this article, we will explain the fundamentals of achromatic lenses, what are achromatic lens used for, the designs of achromts.
High Power Ultrafast Laser Mirrors-You Need to Know
In this article, which is we will be looking at different aspects of ultrafast lasers, including how are ultrafast lasers produced (via mode locking and chirped pulse amplification), the optics needed for a ultrafast femtoline laser setup, the core elements for ultrafast lasers-ultrafast laser, mirrors the technical challenges for ultrafast laser mirrors.
How to Choose Your Fast Timing Scintillators
In this guidance to fast timing scintillators, Shalom EO will use our professional knowledge to help you learn about how to choose the best fast timing scintillators that suits your uses, by facilitating you to understand what is decay time and its implications in the application senario, and offering detailed explanation of the critical performance parameters that you should consider when selecting your scintillator materials.
How ZnS and ZnSe Are Replacing Germanium (Ge) in IR Optics
Due to recent exporting rules, the price of germanium on the global market is surging, and the delivery is much longer than before. Zinc Sulfide (ZnS) and Zinc Selenide (ZnSe) are increasingly used as substitutes for Germanium (Ge) in infrared (IR) optics. This article offers a detailed comparison and explanation of how ZnS and ZnSe are replacing Ge as IR optics in their optical performance, thermal and mechanical properties, and costs.
